“…As more evidence of the effect of vaccination on transmission becomes available, researchers should investigate the how communicating such evidence impacts vaccine attitudes and intentions. This may be especially relevant for increasing vaccination rates in younger age groups who are at much lower risk of death or hospitalisation from COVID-19 and perceive less threat from the virus (Karlsson et al, 2021;Troiano & Nardi, 2021). Another factor we did not examine in the current studies was the impact of message source.…”

The success of mass COVID-19 vaccination campaigns rests on widespread uptake. However, although vaccinations provide good protection, they do not offer full immunity and while they likely reduce transmission of the virus to others, the extent of this remains uncertain. This produces a dilemma for communicators who wish to be transparent about benefits and harms and encourage continued caution in vaccinated individuals but not undermine confidence in an important public health measure. In two large pre-registered experimental studies on quota-sampled UK public participants we investigate the effects of providing transparent communication—including uncertainty—about vaccination effectiveness on decision-making. In Study 1 (n = 2,097) we report that detailed information about COVID-19 vaccines, including results of clinical trials, does not have a significant impact on beliefs about the efficacy of such vaccines, concerns over side effects, or intentions to receive a vaccine. Study 2 (n = 2,217) addressed concerns that highlighting the need to maintain protective behaviours (e.g. social distancing) post-vaccination may lower perceptions of vaccine efficacy and willingness to receive a vaccine. We do not find evidence of this: transparent messages did not significantly reduce perceptions of vaccine efficacy, and in some cases increased perceptions of efficacy. We again report no main effect of messages on intentions to receive a vaccine. The results of both studies suggest that transparently informing people of the limitations of vaccinations does not reduce intentions to be vaccinated but neither does it increase intentions to engage in protective behaviours post-vaccination.

“…COVID-19 infection (no difference observed between those who were infected and those who were not); Concern with COVID-19 (those who were very concerned about being infected were less likely to refuse to cina); I work in healthcare settings (healthcare professionals had a higher acceptance). [3] In this review, there was a high general hesitation of the vaccine in relation to the COVID-19 vaccine, with prevalences varying from 8% to 15% in the world. This phenomenon represents an important problem, because the increase in hesitation leads to falls in coverage and often precedes an outbreak of infectious disease.…”

“…This phenomenon represents an important problem, because the increase in hesitation leads to falls in coverage and often precedes an outbreak of infectious disease. [3] Health professionals should be involved in educating people about the importance and benefits of the vaccine. However, although researchers have begun to develop and evaluate interventions for people who hesitate to vaccinate, current data does not support an intervention method as superior to others, so ongoing development and evaluation of interventions is necessary.…”

“…The World Health Organization (WHO) has defined this behavior as being influenced by a number of factors, including issues of trust (not trusting the vaccine or the supplier), complacency (does not realize the need for a vaccine, does not value the vaccine) and convenience (access). [3] Individuals hesitant about vaccination are a heterogeneous group that maintain varying degrees of indecision about specific vaccines or vaccination in general. They may accept all vaccines, but remain concerned about possible adverse reactions, some may refuse or delay some vaccines, but they accept others, and some individuals may refuse all vaccines.…”
